MULTIPLE GAG-E Specification of Letters Patent.

Serial No. 426,544.

To all whom it 'may concern:

lie it known that I, Gunnar O. Hannan, a citizen of the United States, residing at Beloit, in the county of Bock and State of `Wisconsin, have invented certain new and useful Improvements in Multiple Gages, of which the foliowing is a specification.

rlhe improvement of gages or guides for boards fed to a saw or the like is the main aim and obj eet of my present invention. I propose te use a plurality of parallel guide bars spaced apart the correct and desired distance from the saw, any one of which may be used as a gage or guide for a board, the latter passing beneath the other guide bars located between the chosen or selected one and the saw. The board raises these other guide bars out of the way and temporarily renders them inoperative. Flach of .the gages or guides is hinged, preferably by means of a link, to a support at the forward end of the table of the machine, and the front ends of the guides are arranged 1n stepped relation, that is, they project sucl cessively farther forward, the one most rcmote from the saw extending forwardly the greatest amount. The purpose of this arrangement is to permit the operator or workman to start the board against the side face of the chosen guide bar, and as it is pushed toward the saw it is guided by this bar and passes beneath and raises the other bars between the selected one and the saw, these latter bars riding idly on the top surface of the board.

It is a further object of my invention to construct the guides so that they may lie attached to the ordinary adjustable guiding fence or rail.

On the accompanying sheets of drawings I have illustrated the preferred and most desirable embodiment of my invention, and on the various views like reference characters are applied to the same parts throughout.

On these drawings,-Figure 1 is a pers ective view of a portion of a band saw i lustrating my multiple gage applied to the table; Fig. 2 is a plan view of the construction shown in Fig. 1; Fig. 3 is a side elevation of a part of the band saw equipped with my improved gage; Fig. 4 is a partial edge view and partial section of one of the gages; and Fig. 5 is a side elevation of the same.

In Fig. 1 I have illustrated the table 1() of a band saw adjacent to which is an upright column or post 11 on which a bracket or support 12 is vertically-adjustable, this bracket or support carrying a pair of feed rollers 13 and 14 and a guide-block 15 for a band saw 16. Extended across the table l() is the usual guide fence or rail 17 adjustable toward and from the saw in any approved manner. Near its front end this angle guide fence is supplied with an upstanding slotted bracket 1S detachably carrying a shaft or bar 19 eX- tended toward the saw. Resting on the top face of the table 10 and located between the saw and the fence 17 are a plurality ci parallel guide bars or gages 19, 20, 21, 22, 23, and 24. All of these guide bars have their rear ends turned upwardly at 25 and a portion of them, in the present instance bars 19, 20, and 21, have their forward ends inclined upwardly at 2G. The remaining bars 22, 23, and 24 lie ilat upon the table as the bars 19, 20, and 21 do, but their front ends are not turned up. The forward end of cach bar has a link 27 pivoted thereto at 2S, each link consisting of a pair of side bars or plates 29 and 3() and an intermediate filler 31. The front ends of these links are all rotatably mounted on the shaft or rod 19, and each link is of the same thickness as the guide bar to which it is attached, so that the link forms a part of the gage or guide itself. As is clearly indicated, the front ends of the guide bars are arranged in stepped relation, that is, they project successively farther forward, the bar 24 being longest, while the bar 19 is the shortest. rllo allow for this difference in length of the bars, the links 27 also vary in length. All of these links extend rearwardly from the shaft or rod 19, which construction permits the guide bars and links to be readily raised when a board is pushed beneath them.

The ope-ration of this mechanism is substantially as follows: The operator or workman places the end of the board to be sawed on the table 1() and presses one edge against the upturned end 26 of any one of the guide bars 19, 20 or 21, or against the side face of the link 27 connected to one of the bars 22, 23 or 211. The operator then pushes the board towardthe saw, and, owing to the inclination of the forward ends of the bars and the links attached to other bars, the board readily passes beneath all of those guides or gages between the selected or chosen one and FIJ the saw, raising the same so that they ride idly upon the top face of the board, the latter being guided as it is fed to the saw by the rollers by the side face of the selected guide bar. As soon as the board has passed beyond these guide bars they all drop on to the face of the table into operative position again. It is to be understood that the bar which guides the boards and the other' bars more remote from the saw remain resting on the face of the table. As is obvious, the guide bars Abetween the selected one and the adjustable fence assist in holding the chosen guide bar yfrom displacement or deilection while it is acting upon the board to properly guide its movement to the saw.

Although l have shown the group or set of guide bars as mounted on the adjustable fence, it is apparent that they may otherwise supported, but by mounting them as shown and described they can be readily attached to saws of all kinds without any change or modiiication in the construction of the saw. rlhey form, in reality, an auxiliary device which may be employed or not, and since the shaft or rod 19 may be readily detached or fastened to the bracket 18 the multiple gage maybe applied to or removed from the machine with facility.

The workman, by employing this device, is enabled to saw boards of various widths without adjustment of the guide. As is Well understood, 'where a single guiding fence `or rail is used it is necessary to change its adjustment Alor each width of board to be saWed. rlhis manual adjustment and nia- `nipulation of the guiding fence is wholly -avoided by the employment of my improved multiple gage.

My invention is not limited and restricted to the exact structural features and arrangement of parts shown and described, but these may be varied to a considerable extent without departing from the heart and essence of my invention or sacrificing any of its benefits and advantages.
